Cyclic Process Questions

If $Q$, $E$, and $W$ denote respectively the heat added, change in internal energy, and the work done in a closed cycle process, then:

A thermodynamic system is taken through the cycle $ABCD$ as shown in figure. Heat rejected by the gas during the cycle is:

A thermodynamic system undergoes cyclic process $ABCDA$ as shown in figure. The work done by the system in the cycle is:[Image shows a figure of two identical triangles meeting at a point, forming an 8-shape. Loop 1 is clockwise, Loop 2 is anti-clockwise.]
